| 摘 要： | 为了解决常规的电压空间矢量控制算法中需要进行复杂的正弦函数、反正切函数运算,以及在实际控制系统中实现起来困难,同时也影响系统的动态性能等问题,作者提出了一种基于电压空间矢量的简化算法.该算法根据参考电压矢量在αβ坐标系上的分量直接计算电压空间矢量在各个扇区内的作用时间,简化了运算过程,进行了相关程序的编写,并以DSP TMS320LF2407A作为控制系统的核心进行实验研究,从而得出结论:该算法易于数字化实现,程序简单,运行速度快,动态响应好;用Matlab对系统进行了仿真,仿真结果验证了作者所提出的电压空间矢量算法的正确性与有效性.

| Abstract: | In order to remove the shortages that the conventional space vector control arithmetic needs calculating complex sine function and arctan function,has difficulty in realizing the actual control system and affects dynamic performance,the article presentes a simplified arithmetic.According to the reference voltage's component on the coordinate,the simplified arithmetic directly calculates the acting time of voltage space vector in each sector.With programing and carrying out the experiment with DSP TMS320LF2407A as the core of control system,we reach the excellence that the arithmetic implements digitization easily,the programs are simple,the running speed is quick and the dynamic response is satisfied.Emulating the system with Matlab,we get results certificate the arithmetic that the article presentes is available. |
